The world’s oldest sci-fi tabletop RPG is getting a new version based on one of the world’s most popular rulesets. Traveller 5E has officially landed on BackerKit, courtesy of publisher World’s Largest RPGs. As the name suggests, the game is an atttempt to take the original Traveller mechanics and adapts them for the Dungeons & Dragons 5E rules.
The project is being overseen by veteran designer Timothy Brown (who is best known for co-creating the D&D Dark Sun setting in the 1990s) and has the full support of current Traveller license holder Mongoose Publishing. The crowdfunding campaign officially runs from now until May 15th, 2026 on BackerKit.
It’s a massive shift for Traveller, which has been around for almost 50 years and still retains a solid fan base and an existing, well-respected ruleset. So just what can players expect when 5E heads into Charted Space? Below, we run a scan on all the details.
What is the Traveller RPG?
First published in in 1977, the original Traveller RPG was designed by Marc Miller and published by Game Designers Workshop (GDW). The first edition was known for its focus on hard science fiction, with gameplay revolving around interstellar trade, exploration, starship design and political intrigue in the futuristic setting of the Third Imperium. Early Traveller was also known for its crunchy game mechanics and novel concepts, including a lifepath-career system that famously included the ability to die during character creation (although this feature has since been discontinued from newer editions of the game).
Over the decades, Traveller shuffled through numerous publishers and rulesets, with GDW launching MegaTraveller in 1987 and Traveller: The New Era in 1993. Later versions adapted the setting to popular systems such as GURPS and d20. In 2008, Mongoose Publishing revitalized the line with Mongoose Traveller, leading to a widely praised 2nd edition in 2016 and a rules update in 2022.
What is Traveller 5E?
Traveller 5E is a new sci-fi TTRPG that adapts the popular Traveller game to the Dungeons & Dragons fifth edition rules (which are available for use to publishers under a creative commons license). The lore focuses on a sprawling interstellar future where humanity and various alien species navigate the vastness of jump space. Players take on the role of free traders looking for profit on the fringes of civilization, mercenaries fulfilling dangerous contracts and explorers charting unknown sectors.
The setting includes the new CivX primer, which details a history where ancient human colonists, separated by millennia of slower-than-light travel, are being rediscovered by a thriving civilization that has mastered the jump drive.
Mechanically, the game uses the d20-based proficiency and ability score system of D&D 5E, while also adapting Traveller’s iconic “lifepath” character creation system of the original 1977 game (although it’s not clearly exactly how this system will work). The game also includes 14 career backgrounds, 9 new subclasses (such asi the Hacker and Xenobiologist), as well as a dedicated Psion class.
The system also features rules for starship operations and space combat that incorporate vector-based movement, alongside new GM tools for world-building, robot construction and vehicle design. Notably, the game also retains the old school Traveller mechanic where it is possible for a character to die during creation.
Who is the creative team behind Traveller 5e?
Traveller 5E is being led by a veteran Timothy Brown, who worked on the Traveller: 2300 AD game back in the late 1980s when the license for the game was owned by GDW. Brown later worked for TSR as a Director of Game Development in the early 90s and was responsible for a number of major releases, including launching the Ravenloft, Planescape and Dark Sun settings.
While Mongoose Publishing (who maintains the current Traveller license) will be supporting the project, the work be largely managed by third-party studio World’s Largest RPGs, who is best known for the World’s Largest Dungeon boxed set which was originally published for D&D 3.5 back in 2004 and which was since rereleased for the new D&D 5e rules.
What are the BackerKit options for Traveller 5E?
The project is split across four primary hardcover books and several high-end accessories, as follows:
- The Four Core Books: A comprehensive set consisting of the Core Rules (character creation and gameplay), Gear and Robots (equipment and robotic PCs), Starships (travel and combat) and Worlds and Vehicles (world-building and alien life).
- The CivX Primer: A digital supplement included with every pledge that introduces a new campaign setting and several mission adventures.
- Special Edition & Accessories: Enhanced versions of the books featuring special covers housed in a Metal Slipcase, accompanied by a Magnetic Metal Referee Screen, custom metal dice and detailed starship deck plans.
The BackerKit options are as follows:
- Core Rules PDF ($29 USD): The digital edition of the Core Rules and the CivX Primer PDF.
- Core Rules Hardcover ($79 USD): The physical hardcover and PDF of the Core Rules, plus the CivX Primer and a Vector Movement Hex Map.
- Starter Bundle ($99 USD): Includes the Core Rules hardcover and PDF, the CivX Primer, the hex map and a set of metal dice.
- Low Passage Bundle ($169 USD): An all-digital tier featuring PDFs of all four core books, the Deck Plans Volume One PDF, the Roll20 VTT version and all miniature STLs.
- Jump Drive Bundle ($349 USD): The four regular edition hardcovers housed in the metal slipcase, including the physical Deck Plans book, metal dice and all corresponding PDFs.
- High Passage Bundle ($599 USD): Upgrades to the Special Edition hardcovers and slipcase. Includes the magnetic referee screen, Roll20 VTT and all miniature STL files.
- Starship Beowulf Bundle ($799 USD): Everything from the High Passage tier plus four void dice sets, a galaxy dice bag, a dice tray, a mammoth singularity die and a mystery bag.
- All-In ($999 USD): The “full experience” including everything from the Beowulf tier plus all six physical miniature bundles (Army, Navy, Marine, etc.) and all unlocked stretch goals.
It’s worth noting that the backer options are significantly more expensive than what we typically see for most TTRPGs, particularly when you factor in shipping costs. In fact, as of this writing, the average backer cost is around $360 USD, which again, is extremely high.
What has the fan reaction been like to Traveller 5E?
World’s Largest RPGs has described Traveller 5E as a “gateway” for new fans. And from a business and marketing standpoint that makes a lot of sense, as 5E is easily the most popular ruleset in the TTRPG space. It’s likely the project will attract the attention of many 5E players who may be curious about this new system or who have heard of Traveller before but have never played it.
In fact, as of this writing, the BackerKit has already smashed its initial goal and is close to surpassing a $500K funding milestone (and is likely to generate significantly more as the campaign nears its end).
Reception from existing Traveller RPG fans, however, has been largely negative, at least, if online comments are to be believed. A recent Reddit post from the popular Traveller subReddit, for example, notes: “i can’t properly explain, but someone needing traveller put in 5e terms makes me upset, turning a system that has such creative use and easy customizability into a D&D clone where everything you can do is written out for you just irks me.” The responding user comments are almost unanimously in agreement.
Similarly, on a Bluesky post, award-winning indie TTRPG designer Will Jobst writes: “ttrpg world and the larger hobby game world: reckoning with crowdfunding smoke and mirrors and having frank discussions about what it takes to make art on these platforms and artificial funding goals… traveller 5e: lol”
It’s sentiment shared on Bluesky by TTRPG designer Logan Dean. Searching for “Traveller 5E” on Bluesky, turns up similar results, the vast majority of which are disparaging, again, at least as far as existing fans are concerned on social media.
Final Thoughts
Traveller 5E represents a significant change for Mongoose’s long standing RPG, with the potential to bring the game to an even wider audience. At the same time, it also faces some significant challenges, including potential backlash from existing players. It remains to see if this new iteration of the world’s oldest sci-fi TTRPGs is able to find an audience without alienating its existing fan base.
We’ll be keeping a close eye on Traveller 5E in the days ahead, but in the meantime, crowdfunding runs from now until May 15th, 2026 on BackerKit.
